Three days is not enough to see Sardinia, but it is plenty to fall for it. The trick is to stop treating the island as a beach destination and plan it as a place of cities, ruins and mountains, with the sea as the backdrop. This itinerary uses Cagliari as a base, because the capital has the best choice of hotels, the best food and the easiest day trips, and because everything in it works in spring, autumn and winter as well as summer.
Day one: the old town and the ancient city of the dead
Start in the morning with the hilltop Castello district, the walled medieval heart of Cagliari. Climb from the Bastione di Saint Remy through the lanes to the cathedral, the Pisan towers and the rampart terraces, and consider a guided walk, because the layers of Phoenician, Roman, Pisan, Aragonese and Savoy history are easy to miss on your own. Have a long lunch in the Marina district below, where the trattorias serve culurgiones, fregola and fresh fish. In the afternoon, take a taxi to Tuvixeddu, the great Punic necropolis on the western hill, where a guide can explain the shafts and painted chambers, and finish the day with the light on the pale stone. Dinner in the Marina or near the San Benedetto market is a good way to end.
Day two: the Bronze Age heartland
On the second day, leave the city for the interior. The most rewarding trip is to Su Nuraxi at Barumini, the island's UNESCO World Heritage nuraghe, a vast Bronze Age fortress of dark stone towers and a village built around it. The site is about an hour north of Cagliari, and a small-group tour with a guide helps you understand how the towers were built and used. Many tours pair Barumini with the Giara di Gesturi, a basalt plateau where small wild horses roam among cork oaks, which makes a lovely contrast to the stone. Return to Cagliari in the late afternoon, and treat yourself to an aperitivo on a terrace over the port.
If you would rather see Roman and Phoenician ruins than nuraghi, swap the day for a half-day at Nora, a ruined city on a windswept headland about half an hour from the capital. It has Roman streets, a theatre, baths and mosaics, and sits next to a quiet beach, so it is ideal for a relaxed afternoon with a swim or a walk in the warmer months.
Day three: the headland, the beach and the lagoons
Spend the last day outdoors. A guided walk up the Sella del Diavolo, the Devil's Saddle, climbs the headland that frames the bay and rewards you with views across the whole gulf. Afterwards, walk or take a bus to Poetto, the city's long beach, where even in winter the promenade is lovely on a sunny day. If you have time, visit the Saline Conti Vecchi, the old saltworks near the lagoons, where a small train takes you among the salt pans and, with luck, flamingos. End the trip with a farewell dinner of seafood and a glass of Vermentino.
Where to stay
For a first visit, the Marina district is the easiest choice, because you can walk to Castello, the port and the station. The Miramare on Via Roma is a four-star art hotel with a library and a fireplace in the lobby, and Hotel Italia on Via Sardegna is the value pick. If you prefer a modern design hotel and a quieter street, the T Hotel next to the Lirico theatre has excellent guest scores, though it is a longer walk to the old town. Beach lovers can look at Hotel Nautilus on Poetto.
Practical tips
You do not need a car for this itinerary. Taxis, buses and guided tours cover everything, and Cagliari's centre is compact. Book the Barumini day trip and the Tuvixeddu visit ahead, because small groups fill up in spring and summer, and check opening hours for churches and museums, which shorten in winter. Carry a windproof layer, because the wind can turn a mild day cool, and wear shoes with grip for the polished stone lanes of Castello.
If you have a fourth day
Add the north. Fly or drive to Alghero, a walled Catalan-flavoured port on the northwest coast, and spend a day at Neptune's Grotto and the Palmavera nuraghe. That gives you a very different Sardinia, with its own food, its own dialect and its own coastline, and it is a good reason to plan a second trip. Whatever you choose, do not overpack the schedule. The island rewards slow mornings, long lunches and an unhurried afternoon walk.
